Background: As the only non-European Union (EU) country, Serbia participated in a second point prevalence survey of healthcare-associated infections (HAIs) and antimicrobial use (AMU) organized by the European Centre for Disease Prevention and Control (ECDC) in the EU countries. Here, we aimed to estimate the prevalence of HAI and AMU in patients who had recently undergone a surgery and to compare risk profile, HAI rates, and AMU among surgical patients and non-surgical patients. Methods: A national PPS was performed in 65 Serbian acute-care hospitals, in November 2017. In this paper, the data of 61 hospitals for adult acute-care were analyzed. To ensure the comparability of study design we used the Serbian translation of ECDC case definitions and ECDC PPS protocol. The trained infection control staff, led by a hospital coordinator, reviewed medical records to identify HAI active at the time of the survey and AMU. Only inpatients admitted to the ward before 8 a.m. on the day if the survey were included. Results: A total of 12,478 patients from 61 hospitals for adult acute-care were eligible for inclusion in this study. Significantly higher proportions of surgical patients were female, belonged to the 60-to-79 age group, and were less severely ill. Also, extrinsic factors (invasive devices, hospitalization at the ICU, and prior antibiotics therapy) were more frequent in surgical patients. Prevalence of HAIs was higher among surgical patients (261/3626; 7.2%) than among non-surgical patients (258/8852; 2.9%) (p < 0.0001). The highest prevalence of all HAIs was noted in patients who had kidney transplantation (4/11; 36.4%), while SSIs were the most prevalent among patients who had peripheral vascular bypass surgery (3/15; 20.0%). Non-surgical patients received treatment for community-acquired infections in significantly higher proportion (2664/8852; 64.3) (p < 0.001). Surgical prophylaxis for more than 1 day was applied in 71.4% of surgical patients. Conclusion: We have provided an insight into the burden of HAIs and AMU among Serbia acute-care hospitals, and highlighted several priority areas and targets for quality improvement. © 2021, The Author(s).

Objective: The aim of this study was to use a Serbian-language version of the disease-specific, self-report Sarcoidosis Health Questionnaire (SHQ), which was designed and originally validated in the United States, to assess health status in sarcoidosis patients in Serbia, as well as validating the instrument for use in the country. Methods: This was a cross-sectional study of 346 patients with biopsy-confirmed sarcoidosis. To evaluate the health status of the patients, we used the SHQ, which was translated into Serbian for the purposes of this study. We compared SHQ scores by patient gender and age, as well as by disease duration and treatment. Lower SHQ scores indicate poorer health status. Results: The SHQ scores demonstrated differences in health status among subgroups of the sarcoidosis patients evaluated. Health status was found to be significantly poorer among female patients and older patients, as well as among those with chronic sarcoidosis or extrapulmonary manifestations of the disease. Monotherapy with methotrexate was found to be associated with better health status than was monotherapy with prednisone or combination therapy with prednisone and methotrexate. Conclusions: The SHQ is a reliable, disease-specific, self-report instrument. Although originally designed for use in the United States, the SHQ could be a useful tool for the assessment of health status in various non-English-speaking populations of sarcoidosis patients. © 2016 Sociedade Brasileira de Pneumologia e Tisiologia.

Aim: To provide a comprehensive assessment of burden of selected cancers in Serbia. Method: We calculated disability adjusted life years (DALY) - the sum of the years of life lost (YLL) from premature mortality and the years lived with disability (YLD) - for cancers of stomach, colon and rectum, lung, breast, and cervical cancer for central Serbia and Vojvodina, Serbia and Montenegro. The obtained values were compared with the corresponding values for European region as estimated by the World Health Organization. The study was conducted between October 2002 and September 2003. The cancer burden was estimated for the year 2000. Results: Observed cancers were responsible for 133 689 DALYs (73 197 for men and 60 482 for women). There were significantly more losses because of premature death than disease disability (95.2% vs 4.8% in men P<0.001, and 93.2% vs 6.8% in females, P<0.001). The cancer burden was dominated by lung cancer in men and breast cancer in women. The cancer burden was very small before the age of 35. Conclusion: DALYs per 1000 population were higher in Serbia than in the European region for all observed cancers except for stomach cancer. The participation of a burden caused by disability in the total burden of selected cancers was lower in Serbia than in other European countries, with the greatest differences in colorectal, breast, and cervical cancers.

AIM: To analyze cancer mortality trends in men in Central Serbia during 1985-2006 period. METHODS: Mortality rates and trends for the most frequent cancers in men (lung, stomach, colorectal, pancreatic, and prostate cancer) were calculated. Mortality rates for all cancers were adjusted by direct standardization. Percentage changes of the rates were calculated as the percentage difference between the rates of two successive years and then as a mean of these changes for the entire observed period. Trend lines were estimated using linear regression. RESULTS: Total cancer mortality in men increased, with mean percentage of annual changes being 1.53% (95% confidence interval [CI], -0.09-3.16). Lung, stomach, colorectal, pancreatic, and prostate cancers represented 58.1% and 61.6% of total cancer deaths in 1985 and 2006, respectively. Increasing trends were observed for all investigated cancers: mean annual percentage change for lung cancer was 2.31%(95% CI, 1.03-3.59), for colorectal cancer 2.23% (95% CI, -0.18-4.65), for prostate cancer 3.06% (95% CI, -2.07-8.18), and for pancreatic cancer 1.58% (95% CI, -2.17-5.32). Stomach cancer mortality significantly decreased in age groups 40-49 and 50-59 years. CONCLUSION: The most frequent cancers in men in Central Serbia, i.e., lung, colorectal, prostate, and pancreatic cancer, showed an increasing trend. Only stomach cancer mortality decreased over time.

Background/Aim. Thymoma is the most common mediastinal tumor. The treatment procedures are based on the results from the research of retrospective studies because they are not frequent tumors. The aim of this work was to define common clinical features, therapeutic aspects, survival and recurrence free survival. Methods. This study was performed in the Clinic for Pulmonology, Clinical Centre of Serbia, Belgrade from January 1993 to December 2013. We analyzed 62 patients with histopathologically proven thymoma. The results were obtaind from medical history, physical exam, chest X-ray and/or computed tomography and operational findings or diagnostic procedure reports. Thymomas were clasiffied according to the World Health Organization classifying system, based on histopathological findings, and staged according to the Masaoka-Koga staging system. Results. There were more female (54.8%) patients. Patients were mostly in the seventh decade of life. One third (29%) of the patients were asymptomatic. Cough was the dominant symptom. Myasthenia gravis was the most common paraneoplastic syndrome (12.9%). Solitary tumor was the most common in our patients (61.3%), as well as the tumors larger than 5 cm (52.5%), and noninvasive thymomas (52.5%). The majority of patients (40%) were in the stage I of the disease. The operative approach was conducted in most of the patients (88.7%). A statistically significant difference in survival was in women, patients with solitary tumor, non-invasive thymomas, patients in the stage I of the disease, and those who were operated. The dimension of the tumor mass approached the conventional level of significance. Conclusion. In patients with thymomas, statistically significant survival rate predictors are gender, presence of solitary tumor mass, tumor invasiveness, clinical stage and surgical treatment of the disease. © 2020 Inst.

Background: Hip fractures in the elderly are followed by considerable risk of functional decline and mortality. Questions/purposes: The purposes of this study were to (1) explore predictive factors of functional level at discharge, (2) evaluate 1-year mortality after hip fracture compared with that of the general population, and (3) evaluate the affect of early functional outcome on 1-year mortality in patients operated on for hip fractures. Methods: A total of 228 consecutive patients (average age, 77.6 ± 7.4 years) with hip fractures who met the inclusion criteria were enrolled in an open, prospective, observational cohort study. Functional level at discharge was measured with the motor Functional Independence Measure (FIM) score, which is the most widely accepted functional assessment measure in use in the rehabilitation community. Mortality rates in the study population were calculated in absolute numbers and as the standardized mortality ratio. Multivariate regression analysis was used to explore predictive factors for motor FIM score at discharge and for 1-year mortality adjusted for important baseline variables. Results: Age, health status, cognitive level, preinjury functional level, and pressure sores after hip fracture surgery were independently related to lower discharge motor FIM scores. At 1-year followup, 57 patients (25%; 43 women and 14 men) had died. The 1-year hip fracture mortality rate compared with that of the general population was 31% in our population versus 7% for men and 23% in our population versus 5% for women 65 years or older. The 1-year standardized mortality rate was 341.3 (95% CI, 162.5-520.1) for men and 301.6 (95% CI, 212.4-391.8) for women, respectively. The all-cause mortality rate observed in this group was higher in all age groups and in both sexes when compared with the all-cause age-adjusted mortality of the general population. Motor FIM score at discharge was the only independent predictor of 1-year mortality after hip fracture. Conclusions: Functional level at discharge is the main determinant of long-term mortality in patients with hip fracture. Motor FIM score at discharge is a reliable predictor of mortality and can be recommended for clinical use. Level of Evidence: Level II, prognostic study.

Toxoplasmosis is a globally distributed parasitic zoonosis, affecting approximately one third of the human population. Epidemiological studies on toxoplasmosis conducted in Serbia so far have been focused on women of childbearing age, without a clear insight into the prevalence in the general population. We conducted a cross-sectional study in a representative sample of the healthy adult population consisting of 1095 blood donors of both genders to establish the prevalence and risk factors for Toxoplasma gondii infection. Data on the demographic and clinical characteristics of all study participants, as well as on their lifestyle habits, were collected by means of a questionnaire. The overall prevalence of infection was 20.5% (224/1095) and the avidity of the specific IgG antibodies detected was high in a vast majority of the seropositive donors (98.2%). Interestingly, the remaining 1.8% of the specific IgG positive samples were of borderline avidity (4/224), in complete absence of specific IgM. The multivariate logistic regression analysis showed that independent risk factors included age (from OR (95% CI) 1.9 (1.13–3.28) in the 30–39 age group, to 6.8 (3.27–14.24) in the age group of >60 years), suburban living (OR (95% CI) 2.2 (1.43–3.34)) and contact with soil (OR (95% CI) 1.4 (1.01–1.94)). This first large-scale study on toxoplasmosis in the general population in Serbia shows the lowest prevalence ever reported in this country. Moreover, the novel perspective on risk factors provides an updated basis for future prevention programs. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

Toxoplasmosis, caused by the cosmopolitan protozoan Toxoplasma gondii, has particular implications during pregnancy due to the possible transmission of infection to the fetus. Very few studies have assessed seroprevalence and the risk factors for toxoplasmosis in healthy pregnant women. The aim of this study was to examine the seroprevalence of T. gondii infection in healthy pregnant women and to identify the associated risk factors for toxoplasmosis. The cross-sectional study involved 300 healthy pregnant women who came to the Institute for Blood Transfusion in Belgrade between November 2018 and February 2019 for routine blood group and Rh factor testing before delivery, who were also tested using serological screening for the presence of specific antibodies. Positives were further examined using enzyme immunoassay. Of the total sera of participants analyzed, 38 were positive for specific IgG, resulting in a seroprevalence rate of 12.7% (95% Confidence Interval (CI) 9.1–17.0%). All pregnant women presented negative anti-T. gondii IgM antibodies. The multivariate logistic regression analysis revealed that living in a house with a garden was independently associated with the risk of T. gondii infections, while eating chicken meat was connected with a lower risk compared to eating other types of meat with an odds ratio (OR) of 2.5 (95% CI 1.21–5.02) and an OR of 0.3 (95% CI 0.09–0.83), respectively. Although the prevalence of anti-T. gondii IgG antibodies is relatively low, it is essential to maintain and adapt evidence-based preventive measures for toxoplasmosis continually. © 2023 by the authors.

Hip fracture in elderly people is associated with high morbidity and mortality. Therefore, it is important to identify risk factors that potentially influence outcomes after hip surgery. The main purpose of this study was to evaluate the relationship of anemia at admission and short-term outcomes after hip fracture. We studied 343 community-dwelling patients who underwent surgery for hip fracture from March 2009 to March 2010. Functional mobility at discharge, postoperative complications, hospital length of stay and in-hospital mortality were analyzed in respect to presence and severity of anemia at admission. Anemia (defined as hemoglobin levels < 13.0 g/dl for men and < 12.0g/dl for women) was present in 185 (53.9%) patients, of whom 54 (29.2%) were severely anemic (defined as hemoglobin level 10.0g/dl or below). In multivariate analysis anemia was associated with age, gender (female), type of fracture (intertrochanteric) and American Society of Anesthesiologists (ASA) classification (3 or 4), while severity of anemia was associated with recovery of ambulatory ability at discharge. There was no difference in the incidence of postoperative complication, in-hospital mortality and length of hospital stay between the groups at discharge. Overall anemia at admission is an indicator of poor general health status. Ambulatory recovery in hip fracture patients is independently related to severity of anemia at admission. © Versita Sp. z o.o.

Introduction: The aim of the study was to determine to what extent severe cognitive impairment impacts short-term rehabilitation outcomes of elderly patients with proximal hip fracture. Material and methods: A total of 337 community-dwelling elderly patients with acute hip fracture were observed during a 12-month period at a major teaching hospital in Serbia. Cognitive status was assessed at admission with the Short Portable Mental Status Questionnaire (SPMSQ). Outcome after 4 months was analysed with respect to presence of severe cognitive impairment, defined as an SPMSQ score of < 3. Outcome assessment included presence of postoperative complications, absolute motor Functional Independence Measure (FIM) gain, Activities of Daily Living index (ADL), Instrumental Activities of Daily Living score (IADL), and walking ability. Results: An SPMSQ score of < 3 was observed in 36 patients (10.7%) with acute hip fracture. Patients with an SPMSQ score of < 3 achieved worse short-term outcomes regarding all observed variables. However, cognitive status was found to be an independent predictor only with respect to mortality at 4 months (odds ratio (OR) = 0.969, 95% confidence interval (CI) = 0.947-0.992, p = 0.009). In contrast, pre-fracture motor FIM independently predicted mortality (OR = 2.982, 95% CI = 1.271-7.000, p = 0.012), and preserved walking ability at 4 months follow- up (OR = 0.945, 95% CI = 0.912-0.980, p = 0.002). Correspondingly, pre-fracture ADL was an independent predictor of absolute motor FIM gain at 4 months follow-up (OR = 0.175, 95% CI = 0.405-11.426, p = 0.035). Conclusions: Failure to consider functional status prior to fracture might overestimate the impact of cognitive status on functional outcome of hip fracture patients.

Millions of patients acquire healthcare-associated infections (HAIs) every year, putting them at risk for serious complications and prolonged hospitalization. Point prevalence surveys (PPS), guided by the European Centre for Disease Prevention and Control framework, are one of the primary methods by which countries in the European Union conduct surveillance of HAIs. Serbia, though not in the EU, implemented this approach in its national PPS. The microbiological and antimicrobial resistance (AMR) analyses comprised patients in 61 out of 65 hospitals included in the fourth PPS conducted in November 2017. A total of 515/12,380 (4.2%) of the adult patients included in the PPS had at least one HAI, with intensive care units carrying the highest prevalence of 15.9%. Urinary tract and surgical site infections were the most frequently identified types of HAIs (23.9% and 23.0%, respectively). Enterobacterales comprised almost half (47.0%) of all causative agents, most notably Klebsiella spp. (16.7%). AMR was very high for most pathogens—80.5% of nonfermentative Gram-negative bacilli were resistant to carbapenems whereas 62.9% of Enterobacterales were resistant to third generation cephalosporins. The calculated AMR index of 61% is one of the highest in Europe. Further efforts are needed to reduce the burden of HAIs in Serbia that carry very high resistance rates to antibiotics currently used in clinical practice. © 2022 by the authors.

Background: Nosocomial bloodstream infections (BSI) create a serious health problem in hospitals all over the world. The objectives of our study were to explore putative disease markers and potential risk factors with nosocomial BSI in patients in intensive care units (ICU) and non-ICU patients and to determine risk factors associated with increased 28-day mortality rate in patients with nosocomial BSI acquired in combined medical-surgical ICU. However, the major purposes of this report were to identify epidemiologic differences between nosocomial BSI acquired in ICU and non-ICU, as well as analyses outcomes for patients with nosocomial BSI acquired in ICU. Methods: A 1-year prospective cohort study was performed to determine the incidence of nosocomial BSI in hospitalized patients. Patient characteristics, risk factors related to health care, and source of infection of patients with BSI acquired in non-ICU were compared with those patient with BSI acquired in ICU. Also, nested case-control study of patients to nosocomial BSI acquired in ICU was performed to evaluate outcome. Patients were identified by active surveillance and positive blood culture during the study period. Results: The incidence of nosocomial BSI was 2.2 per 1000 admission in non-ICU patients and 17.4 per 1000 admission in ICU patients. The 28-day crude mortality rate was 69% in ICU patients. A multivariate model showed that nasogastric tube (RR, 25.1; 95% CI: 3.845-163.85; P = .001), mechanical ventilation (RR, 13.04; 95% CI: 1.974-96.136; P = .008), and H2 blockers (RR, 12.16; 95% CI: 1.748-84.623; P = .012) were more prevalent among patients with BSI acquired in ICU, and aggressive procedures (RR, 8.65; 95% CI: 1.70-44.00; P = .009) were more prevalent among patients with BSI acquired in non-ICU patients. Risk factors independently associated with increased 28-day mortality rate in ICU patients were mechanical ventilation (OR, 8.63; 95% CI: 1.5-49.8; P = .016) and SAPS II >40 (OR, 6.0; 95% CI: 1.0-35.7; P = .049). The most common isolated nosocomial BSI pathogens (in both groups of patients) were coagulase-negative staphylococci (21%), Staphylococcus aureus (14%), and Klebsiella species (13%). Klebsiella species was the only organism independently influencing the poor outcome of nosocomial BSI in ICU patients (OR, 4.3; 95% CI: 1.2-15.3; P = .022). Conclusions: Our results show epidemiologic differences between non-ICU and ICU BSI. Also, this study suggests that severity of underlying host conditions, mechanical ventilation, and microbial agents (Klebsiella species) affect the outcome of NBI in patients in ICU.

Introduction: Nosocomial infections (NIs) are a serious health problem in hospitals worldwide and are followed by a series of consequences, medical, judicial, ethical and economic. Objective: The main aim of this study was to assess the magnitude of NIs at the Clinical Centre in Kragujevac. Methods: A prevalence study of nosocomial infections was conducted from 16th till 20th May, 2005, within Second National Prevalence Study of Niš in the Republic of Serbia.& Results The study included 866 patients. 40 patients had a NI, thus the prevalence of patients with NIs and prevalence of NIs was the same, 4.6%. Among NIs, the most frequent were urinary infections (45.0%) followed by surgical-site infections (17.5%), skin and soft tissue infections (15%) and pneumonia (12.5%). The rate of NIs was highest at departments of orthopaedics and traumatological surgery (12.0%), followed by intensive care units (8.0%). Overall, 67.5% (27/40) NIs were culture-proved; the leading pathogens were Escherichia coli (40.0%), followed by gram-negative bacteria (Pseudomonas species, Proteus mirabilis, Enterobacteriaceae with equal frequency of 8.0%). Nosocomial infections were significantly more frequent in patients aged ≥65 years (p<0.05), with longer hospitalization ≥8 days (p<0.00), in intensive care patients (p<0.05), patients with an intravenous catheter (p<0.00), urinary catheter (p<0.00), and those under antibiotic therapy (p<0.00). Conclusion: This study showed that the prevalence of nosocomial infections in our hospital is similar to the prevalence in the developed countries. The study of prevalence provides a prompt insight into basic epidemiological and ethiological characteristics of nosocomial infections, hence identification of hospital priorities and the need to undertake appropriate prevention measures.

Background/Aim. Nosocomial infections (NI) are a serious health problem resulting in an enromous burden of excess morbidity and mortaliti rates, and health care costs. The aim of this study was to assess the prevalence of NI and to identify groups of patients at special risk for NI in the University Clinical Center, Kragujevac, Serbia. Methods. A period prevalence study design was used in this study. A survey of NI included all patients hospitalized in all departments in the University Clinical Center, Kragujevac. Results. Among 764 patients surveyed, the global prevalence rate of patients with at least one NI was 6.2% (95%CI = 5.6-6.8), while the prevalence of NI was 7.1%. The most frequent infections were surgical site infections (14.1%; 95%CI = 12.9-15.3), followed by pneumonia (2.3%; 95%CI = 2.1-2.5) in surgical patients. In medical wards, the most common NI were skin and subcutaneous tissue infections (1.6%l 95%CI = 1.4-1.8), and urinary infections (1.4%; 95%CI = 1.3-1.5). Overall, 85.1% NI were culture-proven; the leading pathogens were Pseudomonas species (40.0%), followed by Staphylococcus species (25.0%), Escherichia coli (22.5%), Proteus mirabilis (17.5%) and Klebsiella-Enterobacter (12.5%). Multivariate logistic regression analysis identified 3 risk factors independently associated with NI appearance: hospital stay ≥ 8 days (p = 0.0015), urinary catheter (p = 0.0022) and antibiotic use (p < 0.001). Conclusion. This study showed that NI are a serious health problem in our hospital. The most common infections were surgical site infections, followed by skin and subcutaneous tissue infection and urinary tract infections. Nosocomial infections were most common in patients in urological and orthopedic departments, and then in intensive care units. Prolonged hospital stay, urinary catheter and antibiotic exposure were risk factors independently associated with NI appearance.

The risk of occupational bloodborne infections (HBV, HCV, and HIV) among healthcare workers remains a serious issue in developing countries. The aim of this study was to estimate occupational exposure to bloodborne infections among general hospital workers in Serbia. This cross-sectional study was conducted in the spring of 2013 and included 5,247 healthcare workers from 17 general hospitals. The questionnaire was anonymous, self-completed, and included socio-demographic information with details of blood and bodily fluid exposure over the career and in the previous year (2012). Significant predictors of sharps injuries were determined with multiple logistic regressions. The distribution of accidents in 2012 was equal between the genders (39 %), but in entire career it was more prevalent in women (67 %). The most vulnerable group were nurses. Most medical doctors, nurses, and laboratory technicians reported stabs or skin contact with patients’ blood/other bodily fluid/tissue as their last accident. Healthcare workers from the north/west part of the country reported a significantly lower number of accidents over the entire career than the rest of the country (p<0.001). The south of Serbia stood out as the most accident-prone in 2012 (p=0.042). © 2018 Institute for Medical Research and Occupational Health. All rights reserved.

Introduction Occupational exposure to blood and body fluids is a serious concern of health care workers and presents a major risk of transmission of infections such as human immuno-deficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Objective The aim of this study was to determine the frequency and circumstances of occupational blood and body fluid exposures among health care workers. Methods Cross-sectional study was conducted in three university hospitals in Belgrade. Anonymous questionnaire was used containing data about demographic characteristics, self-reported blood and body fluid exposures and circumstances of percutaneous injuries. Results Questionnaire was filled in and returned by 216 health care workers (78.2% of nurses and 21.8% of doctors). 60.6% of participants-health care workers had sustained at least one needlestick injury during their professional practice; 25.9% of them in the last 12 months. Of occupational groups, nurses had higher risk to experience needlestick injuries than doctors (p=0.05). The majority of the exposures occurred in the operating theatre (p=0.001). Among factors contributing to the occurrence of needlestick injuries, recapping needles (p=0.003) and decontamination/cleaning instruments after surgery (p=0.001) were more frequent among nurses, while use of a needle before intervention was common among doctors (p=0.004). Only 41.2% of health care workers had reported their injuries to a supervisor in order to obtain medical attention. 50.2% of health care workers were vaccinated with three doses of hepatitis B vaccine. Conclusion There is a high rate of needlestick injuries in the daily hospital routine. Implementation of safety devices would lead to improvement in health and safety of medical staff.
